This exciting full-color book is the most comprehensive text book on DC/AC circuits and machines for electrical students on the market today. It provides complete coverage of concepts relating to electrical theory, as well as giving practical "how-to" examples of many of the common tasks that electricians must perform. The book has been organized so that all relevant information is located within a given chapter, making it easy to access and easy to teach topics in any order. With its visually appealing, easy-to-understand coverage of alternating current theory, and expanded coverage of topics such as transformers and electrical filters, Delmar's Standard Textbook of Electricity, 2E continues to set the standard in DC/AC circuits and machines.

Designed to be used with Delmar's Standard Textbook of Electricity, 5E, this lab manual with experiments provides the opportunity for students to apply what they learned. The manual contains hands-on experiments for each unit of the textbook and been field tested to ensure that all experiments work as planned.

Lab Manual for Introduction to Electricity (ISBN: 0135106222) is available for purchase and can be ordered through your Pearson representative. The lab manual contains over 45 exercises that were written to supplement the text. Among its features: The opening for each exercise ties the activity to the text material, identifies the relevant chapter objectives, and helps the student to connect the activity to working in the field. Early exercises include detailed descriptions of the circuit connections along with step-by-step assembly instructions, helping the student to build the circuits more quickly and efficiently. The circuit descriptions and assembly instructions become more general as students progress through the manual, moving them toward more independent lab activities. In the first half of the manual, circuit diagrams showing how the circuit el- ements are connected and how the circuit is tested are provided along with the circuit schematics, helping the students to make the connection between schematic diagrams and actual component layouts. The labs are intended for use with the Lab-Volti EMS (electromechanical systems) line from Lab-Volti Systems, Inc. with test equipment available from other providers. However, all labs can be adapted to use similar manufacterers.
